Speccaton of Letters Patent.

Patented April 23, 1907.

Application filed June 24,1905. Serial No. 266.890.

10 all, 1u/w11 t may concern,.-

Be it known that I, LEO H. PLEINs, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Ventilatore for Water-Closets, of which the following is a speci'lication.

The invention is applicable to a single stall or to a range of stalls or to a double range of stalls placed back to back. Its object is to provide a simple and efficient ventilator which is especially adapted for use in school houses. It is, however, applicable to water closets generally, regardless of the number of stalls.

The invention consists in the features of novelty that are hereinafter described with reference to the accompanying drawing which is made a part hereof and in which,

Figure l is a vertical section on the line l-LFig. 2, showing a complete water closet and portions `of a second water closet both having ventilators embodying the invention. Fig. 2 is a front elevation of a complete water closet and a fragment of thestall of a second water closet, the former having a ventilator embodying the invention. Fig. 3 is a section on the line l-3, Fig. 1. Fig. 4 is a section showing a modification.

A represents the sides and B the back of the water closet stall. The back supports a cap plate, C, which, in case of only a single stall or a single range of stalls, may extend to the wall and which in the case of a double range of stalls extends to the back wall, B', of the other range. The space, D, between the walls B and B and the cap plate, C, is closed at its ends. It serves to contain the flushing tanks and in addition to this it affords a working space. It also serves as a Ventilating flue or passage, being open at some point or another for the escape of the foul air and gases, and it is this function of it that the present invention is concerned with. It will be observed that the walls, B and B, of the stalls are also the walls of the llue, D, and they .may hereinafter be considered indiscriminately as the back walls of the stalls or the walls of the Ventilating flue.

Installations vary with respect to the loeation of the outlet -from the llue, D. In the drawing I have shown an outlet, E, leading from the top of the flue, D, but m some 1nstances the outlet is through the l'loor and in other instances it is through the end wall 0f the flue, D.

The wall, common to the stall and the ventilating flue is provided with an opening l) which is preferably of rectangular shape and located only a short distance above the bowl F.

Gis a hood located in the stall and secured to the wall thereof so as to conceal the opening b. This hood comprises a front g, two ends g', and flanges g2 and g3, joining the upper edge of the front and the Arear edges of the ends, respectively, and lying in a Vcommon plane, the front g being bounded at its upper edge by a straight line touching the .lane aforesaid, whence it proceeds outward from said plane and downward to the plane of the lower edges of the ends, the ends being bounded at their front edges by the front and at their rear edges by the plane aforesaid, the hood thus constructed being open at its bottom and at its back. It is secured to the wall, by bolts or similar devices, in such relation to the opening b that its upper edge contacts with the wall just above the opening and its lower edge terminates at a horizontal plane some two or three inches, more or less, below the opening and a considerable distance from the surface of the wall so that between the depending portion of the front and the face of the wall an open passage or space is left for the intake of air. As shown in the drawing the upper portion of the front is of curved shape, while its lower portion is straight and parallel with the front of the wall.

In the Ventilating llue and secured to the wall B is a del'lector II having a portion, 7L, or dellector proper, which is located directly opposite the opening, b, and is oblique with respect to the plane of the wall. It has also ends, L, provided with flanges, which fall directly opposite the end `flanges of the hood, G, so that the same screws or bolts secure both the hood and the dellector to the wall.

The dellector proper, h, does not come in contact with the wall, B, a space, 7L, being left between them. The object of this space is to permit any dust or dirt that may fall behind the deflector, which extends from a point below thc opening to a point above it, to escape. The object of this deflector is to give direction to the current of. air passing IOO through the opening, b, and its position with I opening first outward and thence downward,

respect to the opening will depend upon the concealing the opening, and a delector in the position of the outlet from the flue, D.

In Fig. l of the drawing the outlet is shown as being located at the top and hence the deflector is so placed as to direct the air upward. i

In Fig. 4 I have shown the deiiector as being placed so as to deflect the air downward, this being the position it should occupy with a floor outlet.

Another advantage in the use of this delector where two ranges of stalls are placed back to back, is that it prevents cross currents from one stall to another.

It will be seen that the practice of the invention provides an effective local ventilator for each stall, and in addition to this, where a considerable number of the improved ventilators is used, they constitute an edective room ventilator.

What I claim as new and desire to secure by Letters Patent is:

l. The combination with a stall and a ventilating flue having a common wall, said wall having an opening through it, of a hoodlocated in the stall and secured to the wall, said hood proceeding from a point above the opening first outward and thence downward,

concealing the opening, substantially as described.

2. The combination with a stall and a ventilating lue having a common wall, said wall having an opening through it, of a hood located in the stall and secured to the wall, said hood proceeding outward from a point above the opening and thence downward to a point below the opening, substantially as described.

3. The combination with a stall and a venn tilating lue having a common wall, said wall having an opening through it, of a hood located in the stall and secured to the wall,

said hood proceeding outward from a point above the opening and thence downward to a point below the opening, the lower depending portion of the hood being parallel with the wall, substantially as described.

4. The combination with a stall and a ventilating flue having a common'wall, said wall having an opening through it, of a hood located in the stall and secured to the wall, said hood proceeding from a point above the l Hue located opposite the opening, substantially as described.

5. The combination with a stall and a ventilating flue having a common wall, said wall having an opening through it, of a hood located in the stall and secured to the wall, said hood proceeding from a point above the opening iirst outward and thence downward, concealing the opening, and a deilector in the Hue located opposite the opening, the lower margin of said delector being out of contact with the wall so as to leave a space between them, substantially as described.

6. A hood for ventilators, having a front, two ends, and flanges joining the upper edge of the front and the rear edges of the ends, respectively, and lying in a common plane, the front being bounded at its upper edge by a straight line touching said plane, whence it proceeds outward from said plane and downward to the plane of the lower edges of the ends, and the ends being bounded at their front edges by the front and at their rear edges by the plane aforesaid, the hood being open at its bottom and at its back, substantially as described.

7. The combination with a stall and a ventilating ilue, having a common wall, said wall having an unobstructed opening through it, of a hood located in the stall and secured to the wall so as to conceal said opening, said hood having a front, two ends and flanges joining the upper edge of the front and the rear edges of the ends, respectively, and lying in a common plane, the front being bounded at its upper edge by a straight line touching said plane, whence it proceeds outward from said plane and downward to the plane of the lower edges oi the ends, and the ends being bounded at their front edges by the front and at their rear edges Vby the plane aforesaid, said hood being open at its bottom and at its back and being secured to the wall in such position that its lower edge terminates some distance below the opening, substantially as described.
